To all whom itmycoiwom:

*DUsUzEAU, citizen of the Republic of Be it known that I, Rnm'c Gnomes LiioN France, residing at 9 Avenue des Mouli--i lowing is a specification.

This invention consists in a peculiar construction of magneto of the type comprismg a rotating inductor member, which is characterized essentially by the arrange- 1'5 arranged to rotate,

ment and construction of the armature,this latter having theshape of a U between the limbs of which the said inductor member is A practical constructional'form of a magneto with a rotating inductor member acbording to this invention, is illustrated by way of example in the accompanying drawings in which:

Figure 1 is a longitudinal section of the improved magneto, and

F i 2'is a cross section thereof on the line X of Fig. 1.

As shown, the improved magneto comprises essentially an armature B of U-shape whose primary and secondary windings are situated at D between the limbs 7) of the U.

Aninductor member composed of two soft iron ieces E mounted on a non-magnetic core integral with the driving cone sp1ndie is adapted to rotate in the circular cavsurmounted by the magnets a.

to the simple forms of the armature and inductor.

. If the magnetic flux passing through the armature 'core in the downward direction-be considered as being positive and the. flux passing through the armature core 1n the upward direction be considered asbeing negative then the following table E The improved apparatus thus Bpeelficatlonot Letters Patent: Patented Oct, 26

Having now described my invention, what I claim as new and desire to secure by Let ters Patent is:

1. A magneto comprising in combination: a U shaped magnet, pole pieces secured to the branches of said magnet at the ends of a diameter passing through a central axis, a U shaped armature, the limbs of which are located at the ends of a diameter at right angles with the first mentioned diameter, a non-magnetic spacing member arranged coaxially with the said axis, two diametrically opposed inductor members secured to said spacing member, armature limbs having a length substantially equal to the length of the inductor members plus the depth of the winding and the ends of the limbs being in alinement with the outer ends of said inductor members, a rotary shaft to which the outer end of said spacing member is secured and bearing means located beyond the outer end only of the spacing member and in which the rotary shaft is rotatably supported.

2. A magneto comprising in combination: a U shaped magnet, pole pieces secured to the branches of said magnet at the ends of a diameter passing through a central axis,
